Description

Technical Field

[0001] The invention relates to the technical field of 3D printers, in particular to a drive assembly with a quick-release structure for a 3D printer. Background Art

[0002] 3D printer is a technology that converts digital models into physical objects. It uses various materials to build objects by printing layer by layer and is widely used in many fields such as manufacturing, medical treatment, architecture, education and art.

[0003] When using a 3D printer, a drive assembly is required to control the movement of the printer and ensure that the 3D printer can move and operate accurately according to the designed model.

[0004] Current:

[0005] 1. The drive assembly of existing common 3D printers is generally integrated or assembled with multiple screws. When maintenance is required, it is not convenient to disassemble, which affects the efficiency of maintenance work;

[0006] 2. The drive assembly of an existing common 3D printer is usually placed directly on a table when in use. When the table is not level, the drive assembly of the 3D printer is also not level, which may affect the printing accuracy. When the drive assembly of the 3D printer is not level for a long time, it is easy to cause the position of the drive assembly parts of the 3D printer to shift, affecting the printing accuracy.

[0007] 3. The drive assembly of existing ordinary 3D printers only performs driving work and has relatively simple functions. When the print head installed on the drive assembly is in use, the heating element in the print head will reach a high temperature when melting the printing material. Being in a high temperature state for a long time may affect the performance and life of the print head. If the heat cannot be dissipated in time, it is easy to cause the print head to overheat, affecting the stability of the 3D printer when in use. Summary of the invention

[0020] The present invention provides a drive assembly with a quick-release structure for a 3D printer, which has the following beneficial effects:

[0021] The 3D printer uses a driving assembly with a quick-release structure. Through a horizontal adjustment component, when the driving assembly is used, the horizontal state of the support plate can be observed through a level gauge at the bottom of the support plate. When the support plate is in an uneven state, three groups of U-shaped mounting frames, a rotating block, an internally threaded tube, a first threaded rod, a chassis and an internally threaded tube on an anti-skid rubber pad are rotated and adjusted respectively. The rotation of the internally threaded tube can drive the internally threaded tube to move up and down on the first threaded rod, and the support plate can be adjusted to a horizontal state, so that the driving assembly of the 3D printer is in a horizontal state when in use, thereby improving the printing accuracy of the printer.

[0022] The 3D printer uses a driving assembly with a quick-release structure. When the position of the print head needs to be adjusted by using a moving assembly and a position adjustment assembly, the first reduction motor, the second reduction motor and the third reduction motor are respectively started. The first reduction motor is started to drive the T-block to move up and down through the first bevel gear, the connecting rod, the second bevel gear, the third bevel gear, the fourth bevel gear and the second threaded rod. When the two T-blocks move up and down, the position adjustment assembly is driven to move up and down. When the second reduction motor is started, the first moving block is driven to move left and right through the first rotating rod, the first gear and the first toothed belt. When the first moving block moves, the print head mounting seat is driven to move left and right through the two second slide bars. When the third reduction motor is started, the second moving block is driven to move forward and backward through the third rotating rod, the third gear and the second toothed belt. When the second moving block moves, the print head mounting seat is driven to move forward and backward through the two third slide bars, so that the position of the print head installed on the top of the print head mounting seat can be stably adjusted, thereby improving the accuracy of the 3D printer when printing.

[0023] The 3D printer uses a drive assembly with a quick-release structure, through a heat dissipation component. When the drive assembly of the 3D printer is used, when the first reduction motor starts to adjust the position of the print head, the first reduction motor drives the fan blades to rotate through the first rotating rod, the transmission rod, the fifth bevel gear, the sixth bevel gear and the installation rod. When the fan blades rotate, they draw in external air, and the air enters the first ventilation duct and the second ventilation duct respectively through the three-way pipe and the telescopic hose. Then the air is ejected through a number of nozzles on the first ventilation duct and the second ventilation duct, which can drive the air around the print head and the motor to circulate quickly, dissipate the heat of the print head and the motor, and avoid overheating of the print head and the motor due to long-term operation, which affects the printing accuracy of the 3D printer.

[0024] The 3D printer uses a driving assembly with a quick-disassembly structure, through a horizontal adjustment component, a moving component and a position adjustment component. When the driving assembly needs to be maintained, the butterfly screws connecting the fixed frame and the T-block are removed, and then the position adjustment component is moved upward to remove the position adjustment component from the moving component. Then, the butterfly screws connecting the cross-shaped mounting plate and the second fixed shell are removed, and then the second fixed shell is slid backward to remove the second fixed shell, and then the moving component is moved backward to extract the cross-shaped mounting plate from the first fixed shell, and then the moving component is separated from the horizontal adjustment component. The moving component and the horizontal adjustment component can be quickly disassembled, and the adjustment component and the moving component can be disassembled, thereby improving the convenience of maintaining the driving assembly.

[0025] The 3D printer uses a driving assembly with a quick-release structure, through a horizontal adjustment component, a moving component and a position adjustment component. When the driving assembly is maintained and the driving assembly is installed, when the moving component and the horizontal adjustment component are installed, the cross-shaped mounting plate is inserted into the first fixed shell, and then the T-shaped slider on the second fixed shell is inserted into the T-shaped sliding groove at the bottom of the support plate, and then the cross-shaped mounting plate and the second fixed shell are connected by butterfly screws. When the position adjustment component and the moving component are installed, the sliding groove on the fixed frame is aligned with the limit block, the limit block is inserted into the sliding groove of the fixed frame, and then the fixed frame is placed at the bottom of the inner wall of the T-block, and then the fixed frame is connected to the T-block using the butterfly screw, so that the moving component and the horizontal adjustment component can be quickly installed, and the position adjustment component and the moving component can be installed, so that the convenience of installing the driving assembly is improved, thereby improving the work efficiency of maintenance work.
